Unit 3, Lesson 5: Creation of the Elements
Learning Target: I can explain why some elements are formed during the life of a star and others are not.
Class Activities:
1. Students came in- and picked up the Creation of the Elements handout. For their do now, they answered the question at the top of the handout, and copied the following definition onto their vocabulary sheet:
Chemical Elements: A specific type of atom. Each one has its own number of protons and electrons and has its own physical properties. Most elements are formed from stars.
2. We went over the do now, the point of which was to familiarize ourselves with the elements. I then passed out the Creation of Elements opening activity sheet for the groups to do together. If you were absent, don't bother making this up, but I'm attaching it at the bottom for you to look at. I basically want you to realize that everything has multiple elements in it, and they're crucial to our Earth.
3. We watched a video clip. Section 1 saw a different clip; I'm attaching the one I showed my other sections. We discussed it afterwards. You need to know the following: The types of elements created by stars is determined by the star's size, which in turn determines the temperature at the star's core. More complex elements can only be created in large, super hot stars. Some of the rarest elements can only be created in the explosion of stars, called supernovae.
4. Some sections played Elements Bingo. Some sections talked too much and didn't get to.
